The dreaded pulmonary function test
I underwent the lung function test for the ANA B767 recruitment and failed miserably. Blew with all my might until I turned blue but no luck, just hit 68% capacity. Despite all the encouragement and coaching from the guy administering the test, I could not make the required 80%. Was advised to see a pulmonary/sleep specialist. Did the required testing with CO gas and more blowing...got cleared of any lung problem ( specialist said I was born that way, gotta live with it. A capacity of 60 to 70 % is no big deal; he fail to see why the JCAB requirement is such for 80% )
Someone told me that passing the test require the correct technique. Trolled through various threads, only found some vague thingy about taking really small breaths and then big blow. Well that didn't work for me; IS THERE MORE TO THIS? Thanks.
